Highly active and durable chemically ordered Pt-Fe-Co intermetallics as cathode catalysts of membrane-electrode assemblies in polymer electrolyte fuel cells

A cathode catalyst with enhanced activity for the oxygen reduction reaction and high durability is greatly required in polymer electrolyte fuel cells (PEFCs). We report that chemically ordered intermetallics, Pt sub(2)FeCo/C with L1 sub(0) ordered structure and Pt sub(6)FeCo/C with L1 sub(2) ordered...
